DUST-PROOF ASH-SIFTER.

No. 836,a41.

To all whom it Wary concern:

Be it known that I, JosEPH J. DOMEK, Jr., a citizen of the UnitedStates, residing at Ohicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements inDust-Proof Ash-Sifters, of which the following is a specification.

This invention relates to improvements in a device to be used forsifting ashes, so as to separate the same from the unburned pieces offuel, such as coal and the like; and it consists in certainpeculiarities of the construction, novel arrangement, and operation ofthe various parts thereof, as will be hereinafter more fully set forthand specifically claimed.

The principal object of the invention is to provide an ash-sifter whichshall be simple and inexpensive in construction, strong, durable, andeffective in operation, and so made that during the operation of siftingthe ashes, which may be carried on within a room or out of doors, nodust will escape therefrom.

Another object is to provide means whereby the rotary sifter may bemoved back and forth within the outer cylindrical vessel in an easy andnoiseless manner and when desired may be readily removed from saidcylindrical vessel, so that the ashes may be emptied from the latter andthe unburned pieces of fuel from the former.

Other objects and advantages of the invention will be disclosed in thesubjoined description and explanation.

In order to enable others skilled in the art to which my inventionpertains to make and use the same, I will now proceed to describe it,referring to the accompanying drawings, in which- Figure 1 is a frontview in elevation of an ash-sifter embodying my invention, showing thehandle for operating the sifter or sieve.

Fig. 2 is a central vertical sectional view by dotted lines thepositions to which the handles used for removing the sieve or sifter maybe turned when the cover is displaced. Fig. 3 is an enlarged sectionalview of a portion of the upper part of the outer vessel and its cover,showing a portion of the sifter located therein. Fig. 4 is a plan view,partly in section, of a portion of the sifter and a part of the handlefor operating the same and Fig. 5 is a perspective view of a modifiedconstruction of the device.

sponding parts throughout the different views of the drawings.

The reference-numeral 1O designates the outer vessel, which iscylindrical in shape, as shown, and may be made of any suitable size andmaterial, but preferably of metal. Secured to the upper portion of thevessel 10,

each other, are upwardly-extending apertured plates or ears 11, in theapertures of which are secured the ends of a bail 12 used for moving thevessel from one place to another. The top of the vessel 10 is closed bymeans of a cover 13, which is provided at its center with a handle 14for moving the same. This cover is provided with a downturned upperportion of the vessel 10, so as to prevent the escape of dust. At asuitable distance from its upper end the vessel or receptacle 10 isprovided with a horizontally-extending slot 16, over which is placed andsecured to the outer surface of the vessel 10 a plate 17, which has aslot disposed to aline With the slot 16, as will be readily understoodby reference to Figs. 1 and of the drawings.

below the slot 16, the vessel is provided with a number ofinwardly-extending stubshafts 18, on each of which is mounted anantifriotion-roller 19 to serve as rests for the annular rim 20 of thesifter. These stubshafts are usually in the form of a headed screw, asshown in Fig. 3, and may be adjustably held in place by means of nuts 21on the inner and outer surfaces of the vessel 10, the inner nuts alsoserving to hold the rollers 19 at a distance from the outer vessel, thuspermitting them to have free movement and to be adjusted inwardly oroutwardly, so that they may contact with the bottom of the sifter nearits periphery, or inwardly therefrom, or so that sifters of differentdiameters may be used. 7

The sifter consists of an annular rim 20, which is angular incrosssection, as shown in Figs. 2 and 3, and a cylinder 22, which issecured to the vertical portion of the rim 20 and is of suflicient sizeto fit snugly in the vessel 10, yet at a sufficient distance therefromto permit the annular flange on the cover 13 to extend downwardlybetween its upper portion and the upper portion of the outer vessel.Located horizontally on the upper surface of the horizontal part of therim is a annular flange 15, which fits snugly in the and at points aboutdiametrically opposite At suitable points on a horizontal plane, justscreen or sieve 23, which may be held in place by means of a number ofscrews 24 and washers 25 thereunder, which screws engage the horizontalportion of said rim, as is clearly shown in Figs. 2 and 3 of thedrawings. The rim 20 is provided with an inwardly-extend ing lug 26,which has a screw-threaded opening 27 to receive the inner and.screw-threaded end 28 of a handle 29, which is inserted through the slot16 of the outer vessel, as shown in Figs. 1 and 5, and is .used formoving the sifter back and forth.

By reference to Figs. 2 and 3 it will be seen that the rim 20 of thesifter will rest on the rollers 19, so that its movement will be easyand comparatively noiseless. It will also be observed by reference toFig. 2 that the cylindrical portion 22 of the sifter has hinged to itsupper portion, at opposite sides thereof, handles 31, which may beturned to the position indicated by dotted lines in Fig. 2 and are usedfor removing the sifter from the outer vessel.

In Fig. 5 I have shown a modification in the construction of the device,which consists in omitting the cars 11 and bail l2 and securing to thesides of the vessel 10 at opposite points handles 30, used for liftingor transporting the vessel. In this modified construction the bottom ofthe vessel 10 is left open, as shown, so that said vessel may be placedon the ground, when the ashes may be sifted and allowed to fall directlyon the ground instead of being retained in the vessel 10, as in theconstruction illustrated in Figs. 1 and 2 of the drawings and abovedescribed. In some instances I may provide the vessel 10 and the plate17 with a vertical slot 32, which communicates with the slot 1 6, sothat the cylindrical sifter may be lifted out of the vessel 10 withoutremoving the handle 29, which may be done by turning the sifter untilthe portion 28 of the handle is located at a position to enter the slot22, when it is apparent that it may be passed out through said slot.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

In an ash-sifter, the combination with a oylindrical vessel having ahorizontal slot at a suitable distance below its upper end, of a seriesof screw-threaded and headed stubshafts located in said vessel on ahorizontal plane near the said. slot, a roller on each of said shafts, apair of nuts located on each of said shafts one on the inner and theother on the outer side of said vessel, a cylindrical sifter having asieve horizontally located in its bottom and resting on said rollers, ascrew-threaded apertured lug on the sifter, and a handle having athreaded portion to ensaid lug and extending through the slot in theouter vessel, substantially as described.
